A luxury apartment condo recently opened up along the Biltmore's waterfront. Within the first two months, 80% of the standard units in the first ten of the condo's twelve stories were sold. Nonetheless, only two of the eight penthouses, all of which are located in the top two stories of the building, have sold. In order to sell the remaining six penthouses, the corporation that owns the property, should drop the rate of the penthouses by 20%.

Which of the following, if true, would argue against the proposal above?

A:Typically, the very first unit to sell in a luxury condo is a standard unit.

B:Biltmore has recently suffered a recession and economists do not predict an imminent recovery.

C:Four of the six penthouses yet to be sold face the north side of the city, away from the waterfront.

D:There have been so many buyers ready to purchase the penthouses that apartment management has been carefully selecting those applicants with the best credit histories.

E:After the proposed discount each penthouse will only be 15% more costly than a standard unit.
